channel edge

I have installed ubuntu 18.04 64 bits and I want to test the edge channel but the order sudo system-image-cli --switch ubports-touch / 16.04 / edge --progress dots, does not exist and I can not install it. How could I do it?

@ricardo65 Just to clarify. You have Ubuntu 18.04 on your pc/laptop and want to try the edge channel on your device? You need to use ADB. Open a terminal on the pc/laptop type
adb devices - the daemon should start and your device be listed
adb shell - That will get you into your device
Then rerun the sudo system etc again and that's it. Please be aware that edge is not anywhere near day to day use and can break at anytime. Try at your own risk
